LOCOMOTIVE-FRAME GROSS-TIE AND LINK SUPPORT.

Application filed June 24, 1926. Serial No. 118,160.

My invention relates to accessories of locomotive engine frames, and its object is to provide, as an integral structure, a combined cross tie and valve link support, which can be economically manufactured, easily applied to, or removed from, the engine frame, and which is of simple, compact, and rugged construction. A further object is to provide such a combined cross tie and valve link support to which the reverse shaft brackets and the rear guide supports may be readily aplied. I P The improvement claimed is hereinafter fully set forth.

In the accompanying drawing: Figure 1 is a side view, in elevation, of a portion of a locomotive, illustrating an embodiment of my invention applied in connection with a Walschaerts'valve gear; Fig. 2, a plan View of the same; and, Fig. 3, a cross section, on the line a (a of Fig.1.

Heretofore it has been the practice to support the valve links in brackets bolted to the guide yoke, which is usually in the form of a bar of rolled steel, disposed transversely to the main frame, and bolted to brackets secured to the frame members. The reverse shaft brackets were ordinarily bolted either directly to the guide yoke, or to the link support bracket. This construction is objectionable because of the number of parts employed, and the consequent difficulty involved in their manufacture and assembly.

In the practice ofmy invention, referring descriptively to the specific embodiment thereof which is herein exemplified, I provide, as an integral structure, a combined cross tie and valve link support, which possesses great strength, can be economically manufactured, and can bereadily applied to the main side frame members of a locomo- .tive. My improved structure is also adapted bination lever, 14:; radius rod, 15; valve stem, 16; cross. head, 17 and reverse shaft, 18. v The combined cross tie and link support is in the form of an integral casting, adapted to extend from one of the main side frame members, 10, to the other, and for a con siderable distance beyond each of theframe f members, in order to support the links. The casting comprises a bottom wall, 19, formed with two transverse rows of bolt holes, 20,- through which bolts, 21, pass to the main side frame members. Extending vertically from the bottom wall is a front wall, 22, to

which the reverse shaft brackets, 23, are bolted. It is within the contemplation of my invention, however, to formthe reverse shaft brackets as an integral part of the casting. At each end of the castmg is a rectangular boxing, 24, comprising two parallel bars, 25,

26, formed with bearings 27, which support the valve link trunnions, 12. The bars are joined at one end to the front wall, andat the other end are connected, by a tie wall, 28. Each of the bars, 26, is joined throughout its length to the bottom wall. For the purpose of reinforcing the casting, there is pro vided a web, 29, that extends vertically from the rear of the bottom wall, and joins each of the bars, 26.

The improved construction possesses the advantages that it can be readily manufactured, that it has great structural strength, that it obviates multiplicity of parts and bolted connections, and that it can be assembled on the main side frames with a minimum of labor. It is further to he noted that the front wall is adapted as a supportv for the rear guide supports, which are not shown in the drawing.

I claim as my invention and desire to secure by Letters Patent:

1. A combined cross tie and valve link support, formed as an integral casting, com rising a horizontal bottom wall, a vertical ront Wall for supporting reverse shaft bearings,

a pair of bars at each end of the casting for supporting the valve link, and a web joining lili the bottom wall and each of the inner bars of the respective pairs.

2. A combined cross tie and valve link support, comprising a horizontal bottom Wall, provided with holes for bolting the structure to a locomotive frame, a vertical front Wall, a pair of members extending from the 5 front wall, and bearings in said members for a valve link.

3. A combined cross tie and valve link support, comprising a, horizontal bottom wall JAMES G. BLUNT.
